Name
    Math::Permute::Lists - Generate all the permutations of zero or more
    nested lists.

Synopsis
     use Math::Permute::Lists;

     permute {say "@_"}  [1,2],[3,4];

     # 1 2 3 4
     # 1 2 4 3
     # 2 1 3 4
     # 2 1 4 3
     # 3 4 1 2
     # 3 4 2 1
     # 4 3 1 2
     # 4 3 2 1

     permute {say "@_"} 1,[2,[3,4]];

     # 1 2 3 4
     # 1 2 4 3
     # 1 3 4 2
     # 1 4 3 2

Description
    Generate all the permutations of zero or more nested lists using the
    standard Perl metaphor.

    "permute()" returns the number of permutations in both scalar and array
    context.

    "permute()" is 100% Pure Perl.

Export
    The "permute()" function is exported.

Installation
    Standard Module::Build process for building and installing modules:

      perl Build.PL
      ./Build
      ./Build test
      ./Build install

    Or, if you're on a platform (like DOS or Windows) that doesn't require
    the "./" notation, you can do this:

      perl Build.PL
      Build
      Build test
      Build install
